White spot on nipple like in this pic

Amber • 💖💖💖Baby girl #2 due march 2020. Excited momma! 💖💖💖

Im a little concerned. I had a white/yellowish spot on my nipple like in this picture(not my nipple but looked like it)

Took a warm bath and soaked it in the water. Pushed on it a little and this (creamy/pus) stuff came out of it. Im currently 26 weeks pregnant should i contact my doctor about it? Just worried.

Thanks in advance!!
